4 Claims. 1

invention relates to a scriber particular: ly adapted for scribing or markingparallel lines upon linoleum or other material so that an inlay strip may be inserted, usually of another color,

Broadly, it is anobject of my invention to provide a 'simpledevice which can accurately and speedily score parallel lines in order to cut feature stripping from a larger piece of linoleum or other material.

Still another object of my inventionis to pro; vide a device for scribing or marking linoleum or other material in such a manner so that the marking points or needles are exposed to the view of the operator in order to provide better working conditions and greater accuracy,

Another obiect of my invention is to provide a device for scribing parallel lines upon linoleum or likematerial permitting the tool to be either pushed or pulled so that-the scoring line can run close to any obstructions that may be encountered, such as a transverse vvalh I have thereforespaced my'scoring needlesi'the same distance from the outside edges and the same distance f rom the, longitudinal medial line.

Still a further object of my invention is'to provide automatic means for spacing the scribing needles in variable and predetermined widths r'rqm' each other maintaining uniform distance at all times from the longitudinal medial line. Another object of 'my invention is to provide a handle of such size and weight as to present a balanced tool for the user.

Another object of my invention is to providea storage compartment within the handle for storage of extra needles to be used'in connection with the scribing tool.

Another object of my invention is to provide a radius bar that can be readily used 'ineonnec tion with my scribing tool in order to score parallel circles of predetermined widths.

Another object of my invention is to provide a, scribin tool which has an. exceptionahwide range so that parallel: lines may be'scribed both closeto' a guide edgesand far away from same.

Still a further object of my invention, is, to provide a common radius'bar which may be employed with my scribing tool and. the modification of same.

Still-another object is to provide a radiusbar to which scribing tools may be attached'to bot-h ends-in order tomake a multiplicity of; scribing lines uponlinoleum or otherlik'e material."

Referring to the drawings, numeral 30; represents a scriber having a hollow handle 3! which is attached to an extension 32 mean 'qr'a screw 33. The rear of the handle has a threaded opening leading to the interior compartment of the handle for storing extra needles; The rear en of e n l Q l -f y a thli d 93QW 3. A nt l mbe .3 arin a teriorly threaded end extends through" extension 3 32 and is held in position by the screw 33. The opposite end of the central member 35 has a tapered end 36, tapered on both sides of the cen tral line at the same angle. A slot 3! runs along the longitudinal medial line of central member 35. Between central member 35 and extension 32 is a U-shaped bar 38 which is held in rigid position by the tightened screw 33. A pair of opposed pivoted bars 39 are attached to each end between the U-shaped bar 33 by screws 46 and nuts 6 l, permitting bars 39 to pivot laterally. Knurled threaded screw caps 42 are seated upon screws 40. A pair of rigid pivoted bracket arms 43 are pivotally fastened at the opposite ends of bars 36 by pivot pins 44, the opposite ends of bracket arms 43 having arms overlapping one another so that screw 45 may pass through the hollow of said bracket arms 43, the said screw 45 passing through the slot 3?. A wing nut is seated upon screw 65 to fix the movement of bars 39 and bracket arms 43. The extreme ends of bars 39 have openings to permit the insertion of needles 6i which are rigidly held in position within said openings by threaded screws 43. By loosening wing nut 46, bars 39 may be either spread, as shown in Figure 1, or retracted, as shown by the dotted lines in Figure 1, to spread the needles 4! to certain predetermined desired widths or spacings. The movement of the screw 45 longitudinally within the slot 3! will close the bars 39'to spread the needles the same distance from the longitudinal medial line, since the bracket arms 43 are of the same length.

In order to scribe parallel lines, the end of one of the bars 39 is moved against a straight edge bracket (not shown) and the scriber 36 moved parallel to the straight edge, thus causing the needles 41 to scribe parallel lines. If an obstruction appears, such as a projection in the corner of a room, the scriber 36 can be reversed since the scribing needles 4? are operated the same distance from the outer edge of bars 39 and from the longitudinal medial line of the scriber.

In the event it is desired to scribe parallel circles the knurled screw caps 42 are removed and the radius bar 49 is attached. Radius bar 49 has a right angle bend so that the long arm 56 is approximatel in line with needles 41. The short end 43 has two holes and 52 spaced apart the same distance as screws 46, The opposite end has a hole 19 adjacent the end. In order to attach the radius bar the screws 46 are passed through holes 5| and 52 and the caps 42 are then fastened in position upon screws 40. A pivot pin bracket 53 having a substantially rectangular opening 5-3 adapted to receive long arm 50 is movably positioned upon the arm 50 and fixed thereon by knurled screw 55 which is sufliciently long to pass into opening 54. At the lower end of bracket 53 there is an opening for a needle 56 which is firmly positioned by screw 51. In order to cut a circle or are of a predetermined radius bracket 53 is moved along arm 50 until the point of the needle 56 is the desired distance from the needles 41. The screw 55 is then tightened and using needle 56 as the pivot, the tool 30 is then moved about pivot 56 so that the point of needles 4! contact the surface of the linoleum or other material, thus scribing ar'cs or circles of desired radius.

Referring to Figures '7 to 17 inclusive, numeral 66 represents a modified scriber comprising an elongated U-shaped member 6! upon which is seated an upper member 62 and a lower member 63. The looped portion 64 of U-shaped member 6! has a slight projection 65 so that it can be used to make scribing lines on certain irregular surfaces. The upper member 62 and lower member 63 have opposed grooves to slideably receive the legs of the U-shaped member 6!. A knurled screw 66 passes through slot 61 in the upper portion of member 62 and into a threaded hole in the lower member 63. By tightening or loosening screw 66 upper or lower member 62 and 63 may be moved with relation to each other and rigidly fastened to U-shaped member 6|. Upper member 62 has an extension 68 which slides within the U-shaped member 6!. Extension 68 has a chuck 69 for receiving a needle 16. Chuck 69 is held in position by screw "II. The lower member 63 has attached to the bottom thereof by rivets 12 a flexible arm 13. An extension 14 is attached to the end of arm 73. Arm 13 has an opening adjacent its unattached end and adjacent extension 16. As will be noted in Figure 8, needle 16 passes through this opening. If it is desired to pass needle 10 in front of extension 14, the screw 66 is loosened and upper member 62 is moved inwardly upon the U-shaped member while arm '13 is flexed downwardly to permit the needle to pass out of the opening in the flexible arm. Screw 66 is then tightened at any desired distance between the needle 16 and the front of extension 14. If it is desired to scribe a line upon the tread of a stair, extension M can be run along the nosing of the tread, while the needle 10 scribes a line along the linoleum or other material laid upon the stair, in the position shown in Figure 9.

The upper member 62 has an opening 76 at its rear end adapted to receive an end of the long arm 59 of the radius bar. A threaded opening 11 through which screw 18 passes, firmly attaches the end of the arm 56 of the radius bar through hole 19 to the scriber 60, as shown in Figures 15 and 1'7. The pivot pin bracket 53 may be moved along arm 50 so that the needle 56 is spaced the desired distance from the needle ill and using needle 56 as a pivot point, a circle or are may be scribed.

Referring to Figure 16, if it is desired to scribe a line at a further distance from a baseboard, using looped portion 64 of the U-shaped member 6| as a guide, the upper and lower members 62 and 63 may be reversed and seated upon the. legs of the U-shaped member 6|, so that the needle 10 is at a further distance from the loop 64, such distance being set by tightening the screw 66.

By use of my compact scribers either individually or afiixed to the radius bar either singly or in combination, a large variety of scribed lines can be made in parallel relationship and at a greater distance apart than heretofore known in the field of scribing upon linoleum or other surfaces.

It is obvious that various changes and modifications may be made in the details of construction and the arrangement of parts without departing from the general spirit of the invention.
